While I have shown and described certain. embodiments of my invention,It! is to be understood that it is capable of many modifications.Changes, therefore, in the construction and arrangement may be madewithout departing from the spirit and scope or the invention asdisclosed in the appended claims, in which it is my intention to claimall novelty inherent in my invention as broadly as possible in view ofthe prior art.

What I claim as new, and desire to secure by Letters Patent, is:

1. In combination with a car dumping structure provided with railsadapted to carry a car thereon, means for holding a car on the railsduring a dumping operation of the structure, aid means including a dogon the structure lying above a wheel of the car when in position on thestructure, said dog being positively held against vertical movement andyieldingly held against movement in a substantially horizontal plane topermit parts on the car to pass during movement of the car on the rails.

2. In combination with a car dumping structure provided with railsadapted to carry a car thereon, means for holding a car on the railsduring a dumping operation on the structure, said means including a dogon the structure adapted to lie above a wheel of the car when inposition on the structure, said dog being positively held againstvertical movement and yielding held against movement in a substantiallyhorizontal plane.

3. In combination with a car dumping structure provided with railsadapted to carry a car thereon, means for holding a car on the railsduring a dumping operation on the structure, said means including a dogon the structure having an operative position above a Wheel of the carwhen in position on the structure, said dog adapted to be moved toinoperative position upon being engaged by a part on the car in itstravel on the rails to permit such part to pass, and means urging saiddog into operative position.

In combination with a car dumping structure provided with railsadapted to carry a car thereon, means for holding a car on the railsduring a dumping operation on the structure, said means including a dog011 the structure having an operative position above a wheel of the carwhen in position on the structure, said dog being movable in asubstantially horizontal plane from operative position to inoperativeposition.

5. In combination with a car dumping structure provided with railsadapted to carry a car thereon, means for holding a car on the railsduring a dumping operation on the structure, said means including a dogon the structure having an operative position above a wheel of the carwhen in position on the structure, said dog being movable in asubstantially horizontal plane from operative position to inoperativeposition; and means urging said dog into operative position.

6. In combination with a car dumping structure provided with railsadapted to carry a car thereon, means for holding a car on the railsduring a dumping operation on the structure, said means including a dogon the structure having an operative position above a wheel of the carwhen in position on the structure, said dog being pivoted on asubstantially vertical pivot and movable thereon from an operativeposition to an inoperative position.

7. In combination with a car dumping structure provided with railsadapted to carry a car thereon, means for holding a car on the railsduring a dumping operation on the structure, said means including a dogon the structure having an operative position above a wheel of the carwhen in position on the structure, said dog being pivoted on asubstantially vertical pivot and movable thereon from an operativeposition to an inoperative position; and means urging said dog intooperative position.

8. In combination with a car dumping structure provided with railsadapted to carry a car thereon, means for holding a car on the railsduring a dumping operation on the structure, said means including a dogon the structure having an operative position above a wheel of the carwhen in position on the structure, said dog adapted to be moved fromoperative position to inoperative position upon being engaged by a parton the car in the path of which said dog lies during movement of the caron the rails.
